## Characters
### Rei the Number One Star (一番星のレイ, Ichibanboshi no Rei)

    Voiced by: Yūichi Nakamura
The protagonist. Searching for the Ultimate Battle Spirits, 17-year old Rei travels through space in The Number One Star Ship (一番星号, Ichibanboshi gou) with his friends. He is an almost unmatched card battler and is obsessed with the number 1. Generally easygoing, Rei tries to befriend anyone who he battles with. He eats almost nothing but pizza and Stardust Cola filled with ice, and will drink straight from the bottle when he is troubled or sad. He has a fear of ghosts, though he denies it. Rei also has an Ultimate symbol inside of him which guides him to Ultimates, but knows nothing about it. He has no memory of his past and claims to have no interest in remembering it; his earliest memory is of waking up with Ultimate-Siegfried and Ultimate-Odin in hand. After joining up with Kiriga in the Treasure Ship, a physical manifestation of his past self confronts him and forces him to accept his past. At one point, Rei traveled together with Kiriga and Miroku in the Treasure Ship, but lost his memory after sacrificing himself for Kiriga. Despite this, he wants to return to being friends with Miroku.
